Answer:
y = 
Step-by-step explanation:
Given
x(y + 2) = 3x + y ← distribute parenthesis on left side
xy + 2x = 3x + y ( subtract 2x from both sides )
xy = x + y ( subtract y from both sides )
xy - y = x ← factor out y from each term on the left side )
y(x - 1) = x ← divide both sides by (x - 1)
y = 
Answer:
1x
We do n-1 so the first term is 1x
and the pwoer of zero makes the number 1 so the pattern is still correct because 1x1=1
Double check the equation is true
Second term is 1x
1x5=5
If you don't want the equation you just multiply 5 each time
Hope this helps
Step-by-step explanation:
Step-by-step explanation:
2x-y= -1
x-2y= -8
eqn2*2=2x-4y= -16
eqn3- eqn1
-3y=- -15 y=5
2x-5= -1
2x=4 x=2

Answer:
$1.19
Step-by-step explanation:
Let the cost of a cheeseburger be $b and that of a chicken nugget be $n.
From the given information, we can form 2 equations.
9b +4n= 22.37 -----(1)
3b +4n= 15.23 -----(2)
Notice that the 2 equations have '4n' in them. I'll be using elimination method to solve the equation by getting rid of the 4n.
(1) -(2):
9b +4n -(3b +4n)= 22.37 -15.23
9b +4n -3b -4n= 7.14
6b= 7.14 <em>(</em><em>simplify</em><em>)</em>
b= 7.14 ÷6 <em>(</em><em>÷</em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
b= 1.19
Thus, a cheeseburger cost $1.19.
